What is the difference between minimum, low, medium and maximum security facilities?

Minimum Security facilities typically have no fences and there are fewer guards supervising the inmates.

Low Security facilities have one fence with razor wire. These programs often have more guards than in Minimum, and they often have a work program for the inmates.

Medium Security facilities have two fences topped with razor wire and electronic monitoring. The inmates usually live in cells but usually have an opportunity to participate in work and treatment programs. There are more guards per inmate, for greater security.
